Just think, what all things you need if you want to setup an IT company. First, you need an office space, hardware like computers and servers, and software to run the hardware. Then you need round-the-clock electricity for power and cooling system, and IT experts for managing the business. All of these require a lot of capital investment.
If your work increases, you need more space, more computers and servers, more software, more of cooling system and more IT experts. Again lot of capital expense. If your work decreases and you need to shut down your business, all this expenditure will be of no use.
You can eliminate all this heavy expenditure by using cloud computing.
Cloud Computing Benefits in 2023
Cloud computing is a technology that provides resources and services over the Internet. Resources include email messages, schedules, music, photos, videos, games, websites, programs, web apps, servers, storage, and more. Services include accessing software and storing files online. Instead of accessing these resources and services locally on your computer, you can access them on the cloud. Many users choose cloud storage instead of storing data locally on a hard drive or other media. Cloud storage is an Internet service that provides storage facility to computer users.
Some of these resources and services are free, and some are paid. If you are using paid service, then you pay only for the service that you actually use. As a result, you need not make large investments in equipment or staff to support it.
People choose cloud computing for a variety of reasons:
Accessibility: Data and applications are available worldwide from any computer or device with an Internet connection.
Cost Saving: The expense of buying software and high- end hardware shifts away from the user.
Space Saving: Floor space required for servers and other hardware shifts away from the user.
Scalability: It provides the flexibility to increase or decrease computing requirement as per the need.
ADVANTAGES OF CLOUD COMPUTING
There are many advantages of cloud computing.
- It is probably the most cost-efficient method to use, maintain and upgrade. It eliminates the capital expense of buying hardware and software and other infrastructure.
- It allows users to get large storage capacity for storing data and information.
- It allows users to access files on the Internet from any computer or device that has Internet access.
- Users can allow others to access their files on the Internet such as listening to an audio file, watching a video clip, or viewing a photo instead of sending the file to them via an email message.
- It makes data backup easier and less expensive.
- It allows users to view time-critical data and images immediately while away from the main office or location; for example, doctors can view X-ray images from another hospital, home, office or even while being on vacation.
- It provides up-to-date versions of software, as well as upgrades to servers and computer processing power.
Cloud computing is an Internet technology that provides various services to computer users. There are service providers that provide various types of services for free or charge a fee.
Many organizations like Amazon Web Services (AWS), Google Cloud Platform, and Microsoft Azure have started implementing cloud services like storage, network, hardware, and software.
If a user does not have enough storage on a personal computer, storage on the cloud can be utilized. The same type of service is provided by Flickr.com, which can be used to upload images on its server. The service can be used on a desktop, but the Internet is required when images are to be processed on the desktop. Google Docs is used to create documents online. Google Drive is used to store your work online. All these services are available on the cloud.
CHARACTERISTICS OF CLOUD COMPUTING
Using cloud computing, an organization can run its applications on a shared data center. To use an application that runs on the cloud, all that needs to be done is to login with a username and a password, customize it, and start using it. That is the power of cloud computing.
ON DEMAND SELF SERVICE: Users are able to get the cloud computing resources for almost any type of workload on demand and without requiring human interaction, mostly done through a web-based self-service portal. This eliminates the traditional need of IT experts to manage these resources. With a cloud app, you just open a browser, log in, and start working.
ELASTICITY: Suppose, you have an e-commerce business and you are running your business with four servers At the time of Diwali sale, which comes once in a year for a month, your producty demand increases. You need three more servers to cater to your needs. If you purchase the more servers, what will happen after the safe? You need to lock your extra servers for the ne year. This proves to be a major blockage of large investment. With cloud computing companies can scale up the resources as computing need increases and scale down the resources a computing need decreases. This eliminates the need of large investments in the infrastructure
PAY PER USE: In the cloud computing, your computer resources are measured, and you only pay for the resources that you use.
RESOURCE POOLING: Resource pooling allows cloud providers to pool large scale IT resources to serve multiple cloud consumers. The cloud enables many users to enter and use data within the particular software hosted in the cloud at the same time, from any location, and at any time. This is an attractive feature for multiple business offices and sales teams that work usually outside the main office.
TYPES OF CLOUD
- PRIVATE CLOUD: A private cloud is a proprietary architecture subscribed to by an organization. It provides hosted services to the users within the organization. This is protected by security to form a barrier against the outside world and to access hosted services from the private cloud.
- PUBLIC CLOUD: A public cloud is not proprietary of any organization. The services provided in these clouds can be accessed by any organization or individual.
- HYBRID CLOUD: In a hybrid cloud, the services are offered to a limited and well-defined number of users. The hybrid cloud allows the Internet to be used as a desktop, it is a combination of private and public cloud.
- COMMUNITY CLOUD: In community cloud, the services are offered to a group of organizations or community with common interests.
SERVICES OF CLOUD COMPUTING
Cloud computing services are based on a “pay as you go” model. Consumers and organizations rely on cloud computing services to manage IT infrastructure (infrastructure as a service), provide software applications (software as a service), and create, test, and deploy applications using web based development tools (platform as a service).
INFRASTRUCTURE AS A SERVICE (laas): laaS provides IT infrastructure like servers, storage. network operating systems over the Internet on ‘pay as you go’ basis. It is the most flexible cloud computing model and allows companies to scale storage, processing power, or bandwidth, up or down as needed. For example, retailers may need to increase these capabilities to accommodate additional traffic to their websites during shopping seasons. When the season ends, retailers can easily reduce these settings.
SOFTWARE AS A SERVICE (SaaS): SaaS is a method for delivering software applications over the Internet, on demand and typically, on a subscription basis. Users connect to this application over the Internet, usually through a web browser on their phone, tablet or PC..
PLATFORM AS A SERVICE (PaaS): PaaS provides a cloud platform and allows developers to create, test, and run their program, website, web app, etc. without having to purchase the hardware and software.
